Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473906, here are decompositions:

5 + 31473901 = 31473906
19 + 31473887 = 31473906
43 + 31473863 = 31473906
59 + 31473847 = 31473906
67 + 31473839 = 31473906
97 + 31473809 = 31473906
127 + 31473779 = 31473906
173 + 31473733 = 31473906

Showing the first eight; more decompositions exist.
